2. Description of the Related Art Conventionally, in a mechanical timepiece that is driven by using a mechanical energy storage unit such as a mainspring, in addition to a manual winding head that is a mechanical energy manual input unit for winding a mainspring, a rotary weight is used. An automatic winding head, which is an automatic input unit of mechanical energy used, may be provided. At this time, conventionally, in order to prevent the manual winding part and the automatic winding part from interfering with each other, the manual winding part and the automatic winding part are generally arranged on opposite sides of a barrel with a mainspring. Target.

By the way, in recent years, mechanical energy when the mainspring is opened is converted into electric energy by a generator, which is a power generation unit, and the rotation control means is operated by the electric energy to determine the current value flowing in the coil of the generator. An electronically controlled mechanical timepiece has been developed which controls and accurately drives a pointer fixed to a train wheel to accurately display time (Japanese Patent Laid-Open No. 8-575).
No. 8).

[0004]

However, in such an electronically controlled mechanical timepiece, when both a manual hoist and an automatic hoist are provided, space efficiency is poor and miniaturization is difficult. was there.

That is, in an electronically controlled mechanical timepiece, there are two relatively large parts, a mainspring and a generator. Since these also have a relatively large thickness dimension, they are arranged at different plane positions from the other components in the movement. In addition, a train wheel that transmits the rotational force from the mainspring to the generator is arranged at a position adjacent to the manual winding portion of the barrel. For this reason, the automatic winding part, which is arranged on the opposite side of the manual winding part with the barrel between them, is arranged close to the generator. At this time, the generator has the largest thickness dimension because the coil is wound, and when the automatic winding head is placed on the generator, the thickness dimension of the timepiece (movement) becomes large.

On the other hand, in order to reduce the thickness, it is necessary to shift the position of the generator to make the plane positions of the automatic winding section and the generator different from each other, resulting in an increase in the area of the movement. Therefore, in an electronically controlled mechanical timepiece, when both a manual hoist and an automatic hoist are incorporated, the movement becomes thicker and the plane size becomes larger.
There is a problem that it is difficult to downsize a watch. Further, not only the electronically controlled mechanical timepiece, but also various kinds of timing devices having a mechanical energy storage unit such as a mainspring and a generator, the same problem occurs when both the manual hoisting and the automatic hoisting are provided. There is.

An object of the present invention is to provide a timepiece device having a mechanical energy storage part and a power generation part, which can be provided with both a mechanical energy manual input part and a mechanical energy automatic input part and can be miniaturized. To provide.

By the way, the circuit control means for adjusting the speed of the pointer is provided with a circuit board for forming an electric circuit connected to the generator. In order to reduce the plane size of the movement, this circuit board is usually arranged at a position that overlaps with a part of the coil of the generator or a part of the barrel in a plane. However, in such a circuit board layout structure,
Since the movement becomes thick due to the overlapping portion with other parts, there is a problem that the miniaturization of the timepiece is hindered.

Another object of the present invention is to provide a circuit board for forming an electric circuit, which is connected to the power generation section, in a timing device having a mechanical energy storage section and a power generation section, and can be miniaturized. To provide a timekeeping device.

SUMMARY OF THE INVENTION The present invention comprises a mechanical energy storage section for storing mechanical energy, and a power generation section for converting mechanical energy stored in the mechanical energy storage section into electrical energy. A timekeeping device comprising: a mechanical energy manual input unit for manually inputting mechanical energy into the mechanical energy storage unit; and a mechanical energy automatic input unit for automatically inputting mechanical energy into the mechanical energy storage unit. And a mechanical energy manual input section and a mechanical energy automatic input section are provided on one side (first side) of the mechanical energy storage section, and the power generation section sandwiches the mechanical energy storage section between the mechanical energy storage section and the mechanical energy storage section. It is characterized in that it is provided on the other side (second side) of the mechanical energy storage section which is the opposite side of the manual energy manual input section and the mechanical energy automatic input section. At this time, a spiral wound spiral spring or the like can be used as the mechanical energy storage unit.

According to the present invention as described above, since the mechanical energy manual input section and the mechanical energy automatic input section are provided at positions opposite to the power generation section with the mechanical energy storage section interposed therebetween, The automatic mechanical energy input section does not overlap. Therefore, in order to prevent the increase in the thickness dimension of the movement due to the overlapping of the power generation section and the mechanical energy automatic input section, and the increase in the thickness dimension, the power generation section and the mechanical energy automatic input section should not overlap in a plane. There is no increase in the plane size of the movement caused by shifting the position. As a result, the space efficiency inside the timekeeping device is improved, the movement area and thickness can be suppressed from increasing, and the timekeeping device can be downsized even if it is equipped with an automatic mechanical energy input unit such as an automatic winding mechanism. It becomes possible.

Further, since most of the parts constituting the mechanical energy manual input part and the mechanical energy automatic input part are made of iron, if used for a long period of time, abrasion powder between parts may cause abrasion powder. . Further, when the power generation section is close to the mechanical energy manual input section and the mechanical energy automatic input section, the abrasion powder may enter the power generation section and stop the power generation section.
Therefore, if the mechanical energy manual input unit and the mechanical energy automatic input unit are provided at positions opposite to the power generation unit with the mechanical energy storage unit interposed therebetween as in the present invention, the mechanical energy manual input unit is provided. Also, the mechanical energy automatic input unit and the power generation unit can be separated from each other by the width dimension of the mechanical energy storage unit, which almost prevents the intrusion of wear debris into the power generation unit.

Further, most of the mechanical energy manual input section and the mechanical energy automatic input section are made of iron. Therefore, if these parts are arranged close to the power generation section, leakage from the power generation section will occur. There is a risk that iron loss may occur due to magnetic flux and the like, and magnetic resistance performance may also deteriorate. Therefore, if the mechanical energy manual input unit and the mechanical energy automatic input unit are provided at positions opposite to the power generation unit with the mechanical energy storage unit interposed therebetween as in the present invention, it is possible to move away from the power generation unit. Therefore, it is possible to suppress the occurrence of iron loss in the mechanical energy manual input unit and the mechanical energy automatic input unit, and it is possible to improve the magnetic resistance performance.

Further, since the winding stem, which is also a mechanical energy manual input section, is usually capable of projecting and retracting with respect to the main body of the timing device, there is a risk that moisture or the like will enter the inside of the device from the winding stem portion. . If this water or the like enters the power generation unit, the power generation unit may be damaged. Therefore, if the mechanical energy manual input unit and the mechanical energy automatic input unit are arranged in the vicinity of the winding stem and the power generation unit is arranged away from the winding stem portion with the mechanical energy storage unit interposed, moisture or the like will be generated in the power generation unit. There is almost no risk of infiltration, and the durability of the timing device can be improved.

In the above, the mechanical energy transmission means for transmitting the mechanical energy accumulated in the mechanical energy accumulating portion to the rotor of the power generating portion, the mechanical energy manual input portion and the mechanical energy automatic input portion, It is desirable to place it between the power generation unit. Here, the mechanical energy transmission means includes a train wheel, a timing belt and a pulley,
Consists of chains and sprocket wheels.
According to this structure, since the mechanical energy transmission means such as the train wheel is arranged between the mechanical energy manual input section and the mechanical energy automatic input section and the power generation section, a high torque is applied to the mechanical energy transmission section. The abrasion powder that tends to be generated in the manual energy manual input unit and the mechanical energy automatic input unit is less likely to enter the power generation unit (particularly the rotor), and the performance of the power generation unit is not impaired.

Further, the timekeeping device of the present invention comprises a mechanical energy storage section for storing mechanical energy, and a power generation section for converting the mechanical energy stored in the mechanical energy storage section into electrical energy. A time measuring device, wherein
External operation of the mechanical energy in the mechanical energy storage unit
Mechanical energy manual input section for manual input of members
And the mechanical energy is stored in the mechanical energy storage unit.
With automatic input of mechanical energy to automatically input,
The external operation member, the mechanical energy manual input section, the front
Automatic mechanical energy input unit, mechanical energy storage
Section and the power generation section are arranged in this order along the circumferential direction.
It is characterized by being placed . According to the present invention as described above, since the mechanical energy storage unit is arranged between the mechanical energy manual input unit and the mechanical energy automatic input unit and the power generation unit, the power generation unit and the mechanical energy automatic input unit. There is no overlap with the department. Therefore, the space efficiency inside the timing device is improved, the movement area and thickness can be suppressed from increasing, and the timing device can be downsized even when the mechanical energy automatic input unit such as the automatic winding mechanism is provided. Is possible. Further, even if abrasion powder is generated in the mechanical energy manual input unit and the mechanical energy automatic input unit, the intrusion of the abrasion powder into the power generation unit is almost prevented, and the performance deterioration can be prevented. Further, since it is possible to suppress the occurrence of iron loss in each input section due to leakage magnetic flux from the power generation section, it is possible to improve the magnetic resistance performance. In addition, since the power generation unit is located away from the external operation member such as the crown that operates the mechanical energy manual input unit, there is almost no risk of water or the like entering the power generation unit, and the durability of the timing device is improved. Is possible.

The above-described timekeeping device includes an energy holding amount display unit for displaying the stored amount of mechanical energy stored in the mechanical energy storage unit, and the energy holding amount display unit includes the mechanical energy storage unit and the aforesaid mechanical energy storage unit. It is desirable to be provided between the power generation unit and the power generation unit. At this time, if the mechanical energy storage unit is configured by a spiral wound spiral spring, the energy storage amount display unit is configured by a spiral spring residual amount display mechanism for displaying the spiral spiral wound residual amount. It is preferable. Such an energy holding amount display unit is usually thin and is arranged on the dial side. For this reason, the energy holding amount display section can be arranged so as to overlap a part of the power generation section, which makes it possible to effectively use the space on the dial side between the mechanical energy storage section and the power generation section. Becomes Further, when the energy holding amount display unit is the mainspring remaining amount display mechanism, the structure of the mainspring remaining amount display mechanism can be simplified by providing the mainspring remaining amount display mechanism in the vicinity of the mainspring, which is the mechanical energy storage unit. Also from this point, the space efficiency inside the device can be improved. Further, the mechanical energy manual input unit includes a manual winding wheel train that is manually rotated, and the mechanical energy automatic input unit is an automatic winding train that inputs mechanical energy to the mechanical energy storage unit. Prepare,
The hand-wound train wheel is preferably configured to input mechanical energy into the mechanical energy storage via an automatic winding train wheel.

With this arrangement, the automatic winding train is shared by the respective input sections, as compared with the case where the manual winding train and the automatic winding train are independently provided, so that the number of parts of the apparatus is reduced. It becomes possible. This makes it easier to reduce the size of the timing device.

Further, the above-mentioned mechanical energy storage unit is
It is a spiral wound spiral spring, and the mechanical energy automatic input unit preferably includes an excessive winding prevention mechanism for preventing excessive winding of the spiral spring. With this configuration, it is possible to easily prevent the mainspring from being excessively wound, and it is easy to prevent damage to the mainspring due to excessive winding.

Further, it is desirable that the above-mentioned excessive winding-up prevention mechanism is provided with a mechanism for slipping or deforming a part of the mechanical energy automatic input section. For example, it is desirable that the above-described excessive hoisting prevention mechanism is provided with a slip mechanism that slips a part of the gears of the automatic winding wheel train and the pinion provided in the mechanical energy automatic input unit. Usually, to prevent excessive winding of the mainspring, a slip structure such as a slipping attachment, which is a leaf spring having a length dimension of about one circumference of the mainspring and being thicker than the mainspring, is attached to the mainspring. . However, this causes a problem that the effective length dimension of the mainspring is shortened and it is difficult to lengthen the operation duration of the timing device. Therefore, according to the present invention, since the excessive overwinding prevention mechanism including the slip mechanism is provided in the mechanical energy automatic input unit,
The conventional slipping attachment is no longer required, and the effective length of the mainspring can be increased. This makes it possible to prolong the operation duration of the timing device.

Further, the above-mentioned automatic mechanical energy input section is provided with an automatic winding lever for automatically winding up a mainspring, and the excessive overwinding prevention mechanism is provided with a deformation section provided in a part of the automatic winding lever. It may be configured.
With this configuration, it is possible to easily prevent the mainspring from excessively winding up by the deforming portion provided on the automatic winding lever.
From this point as well, the conventional slip structure such as the slipping attachment becomes unnecessary. Further, since the conventional slipping attachment uses friction, it has to be designed so that the friction state does not change even when it is used for a long period of time. Since the prevention is performed by the deformable portion provided in the automatic winding lever, maintenance of the frictional state is unnecessary, stable operation can be realized for a long period of time with a simple configuration, and the cost of the device can be reduced.

On the other hand, the timekeeping device of the present invention comprises a circuit board having an electric circuit connected to the power generation part, and the mechanical energy storage part and the power generation part are circles of the timekeeping device. The circuit boards are arranged close to each other in a part of the circumferential direction, one end side of the circuit board is connected to the power generation section near the mechanical energy storage section, and the other end side of the circuit board is connected to the mechanical energy storage section. Located near the side opposite the side,
Other parts except the one end side are the power generation section, the mechanical energy storage section, the manual winding wheel train forming the mechanical energy manual input section, and the automatic winding wheel forming the mechanical energy automatic input section. It is characterized in that they are not overlapped in a plane and are arranged along the other part of the timing device except a part in the circumferential direction. In such a case, since the mechanical energy storage section and the power generation section are arranged close to each other in a part of the timepiece device in the circumferential direction, the mechanical energy storage part and the power generation part are other parts in the circumferential direction (remaining parts). Especially, the arrangement space of the portion close to the outer peripheral side can be continuously used in the circumferential direction. By using the continuous space on the outer peripheral side, the circuit board does not overlap the power generation section and the mechanical energy storage section at all (except the connection section with the power generation section), and the plane size of the timepiece device is reduced. It can be made thinner while maintaining it, and can be made smaller. It is preferable that the circuit board has a substantially crescent-shaped plane, and an electronic circuit component for controlling the power generation unit is mounted at a substantially central position between both ends of the circuit board. Further, it is desirable that the circuit board has flexibility, and by doing so, for example, the circuit board can be bent or curved in the thickness direction of the timepiece device and can be arranged in a narrow arrangement. Can flexibly accommodate space.

It is preferable that the circuit board has a substantially crescent-shaped plane, and an electronic circuit component for controlling the power generation section is mounted at a substantially central position between both ends of the circuit board. In the crescent-shaped circuit board, the width at the center side is larger than that at both ends, so by using such a wide portion, electronic circuit components such as a crystal oscillator or an IC can be reliably mounted. . If there is enough mounting space, a storage capacitor, a rectifying smoothing capacitor, or the like may be mounted.

The display cylinder 56 is provided with a display needle 57 that indicates the remaining winding amount of the mainspring 1. The mainspring remaining amount display mechanism 5 is configured by a so-called planetary gear mechanism in which the display wheel 55 is a sun wheel and the second display transmission wheel 53 provided on the third display transmission wheel 54 is a planet wheel.

Accordingly, when the ratchet wheel 11 is rotated by the winding operation of the mainspring 1, the torque thereof is 10%.
From 1 to the first display transmission wheel 51. Here, when the mainspring 1 is wound up, the barrel wheel 10a is in a stopped state, so that the intermediate display wheel 52 and the third display transmission wheel 54 are in a fixed state. Therefore, the second display transmission wheel 53 that meshes with the pinion 51a of the first display transmission wheel 51 only rotates on the spot, and the rotation is transmitted from the display gear 55a to the display wheel 55, and the display cylinder 56 and the needle 57 are moved. Rotate. On the other hand, when the mainspring 1 is rewound, the square hole wheel 11 is stopped, so that the barrel head Makana 101 and the first display transmission wheel 51 are stopped. When the barrel wheel 10a is rotated, the torque is transmitted from the barrel pinion 102 to the intermediate display wheel 52 and the third display transmission wheel 54. Then, since the first display transmission wheel 51 is fixed, the second display transmission wheel 53 revolves around the pinion 51a while rotating, and the rotation is transmitted from the display gear 55a to the display wheel 55, and the display cylinder 56 is moved. Rotate. At this time, since the display cylinder 56 rotates in the opposite direction to that at the time of winding, the display needle 57 also rotates in the opposite direction. Therefore, the winding remaining amount of the mainspring 1 is displayed by the hand 57, and the remaining amount of the time duration of the timepiece can be visually checked.

The mainspring remaining amount display mechanism 5 is shown in FIGS.
As shown in FIG. 3, since it is thin, it is arranged to partially overlap the generator 2 in plan view, that is, it is arranged on the dial side between the barrel wheel 10 and the generator 2.

According to the first embodiment as described above, the following effects can be obtained. (1) Replace the manual winding top 3 and the automatic winding top 4 with the mainspring 1.
Since it is provided on the opposite side of the generator 2 with the generator sandwiched in between, it is not necessary to stack the generator 2 and the automatic winding portion 4 in the thickness direction of the timepiece. For this reason, the movement of the generator 2 and the automatic winding portion 4 overlaps and the movement becomes thick, and the plane size of the movement is reduced by arranging the generator 2 away from the barrel wheel 10 to a position where the generator 2 does not overlap with the automatic winding portion 4. It does not increase. As a result, the space efficiency inside the timepiece is improved, an increase in the area and thickness of the movement can be suppressed, and the timepiece can be downsized even when the manual winding portion 3 and the automatic winding portion 4 are provided. (2) Replace the manual winding part 3 and the automatic winding part 4 with the mainspring 1.
Since it is provided at a position on the opposite side of the generator 2 with the power generator 2 interposed therebetween, the generator 2 can be separated from the manual winding portion 3 and the automatic winding portion 4 by the space of the barrel wheel 10. This allows
Even if abrasion powder is generated in the manual winding portion 3 or the automatic winding portion 4 which has many steel parts by long-term use, it is possible to almost prevent the abrasion powder from entering the generator 2. Therefore, the probability of failure can be further reduced, and the maintenance work can be reduced. (3) Further, since the manual hoisting portion 3 and the automatic hoisting portion 4 can be arranged apart from the generator 2, the leakage magnetic flux to the manual hoisting portion 3 and the automatic hoisting portion 4 can be reduced, and the occurrence of iron loss and the like can be suppressed. You can Therefore, the anti-magnetic performance of the timepiece can be improved. (4) Replace the manual hoist 3 and the automatic hoist 4 with the manual hoist 3.
Since the generator 2 is arranged in the vicinity of the winding stem 31 and the generator 2 is placed away from the winding stem 31 part with the mainspring 1 interposed therebetween, there is almost no possibility that moisture or the like will enter the generator 2 and the durability of the timepiece is improved. Can be improved. (5) Since the mainspring remaining amount display mechanism 5 which is thin and can be arranged on a part of the power generator 2 is provided between the mainspring 1 and the power generator 2, the characters between the mainspring 1 and the power generator 2 are arranged. The space on the board side can be effectively used.

Further, since the mainspring remaining amount display mechanism 5 may have a relatively small strength, it can be constituted by a non-steel part having excellent magnetic resistance such as brass. Therefore, even if it is arranged close to the generator 2, it is possible to prevent the deterioration of the magnetic resistance and the occurrence of a failure due to abrasion powder. (6) Since the manual winding wheel train 34 is configured to input mechanical energy to the mainspring 1 via the automatic winding wheel train 43, the manual winding wheel train 34 and the automatic winding wheel train 43 are independent of each other. Since the automatic winding train 43 is shared by the respective winding upper portions 3 and 4, the number of parts of the timepiece can be reduced as compared with the case where the automatic winding train 43 is provided. As a result, an efficient layout design can be performed, the number of parts can be reduced, the timepiece can be more easily downsized, and the cost can be reduced. For example, when the layout is such that the round hole wheel 35 that meshes with the pinion wheel 33 directly meshes with the square hole wheel 11, the transmission wheel 44 must be moved in the clockwise direction in order to avoid the round hole wheel 35. As a result, the skirt portion of the rotary weight 41 (the outer peripheral edge portion of the rotary weight) cannot be made large, and the rotation startability of the rotary weight 41 is deteriorated. On the other hand, the transmission vehicle 44
If the circular hole wheel 35 is moved to the inner side (center side of the movement) and arranged without moving the position of, the pinion wheel 33 and the clutch wheel 32 must also be moved inward, which makes layout of the calendar correction mechanism difficult. become. On the other hand, the automatic wheel train 43 does not have to directly engage the round wheel 35 with the square wheel 11.
Since the transmission wheel 44 is used, the layout of each vehicle is facilitated, a layout with high space efficiency can be realized, and the timepiece can be miniaturized. (7) As the automatic winding part 4 adopts the pawl lever type having the smallest number of constituent trains, the space for disposing the winding parts 3, 4 can be made small, and the timepiece can be made more compact. (8) Since the round hole wheel 35 of the manual winding upper portion 3 is composed of two pieces, that is, the round hole gear 35a and the round hole pinion 35b, the manual winding portion 3 easily winds up even when the mainspring 1 having a large torque is used. be able to. That is, in the electronically controlled mechanical timepiece as in the present embodiment, in order to stably rotate the rotor 21 at a high torque and increase the duration, in terms of power generation efficiency of converting the rotational torque from the mainspring 1 into electric power, A mainspring 1 having a strong torque is used. Therefore, the hand-wound crown torque tends to be high, and if the automatic winding section 4 is provided, the load of the automatic winding train wheel 43 is also added to the crown torque. Torque increases by about 40% or more. Conventionally, the winding torque of the crown is 30 to 40 gfcm, and even if a large crown is attached, the limit is about 70 gfcm. For this reason, the hand-wound wheel train 34 is attached to the wheel 33 and the round wheel 3
5. It is difficult to wind the mainspring 1 when it is configured only with the square ratchet wheel 11. On the other hand, as in the present embodiment, the round hole gear 35
a, a round hole pinion 35b, and a round hole transmission wheel 36 are provided to increase the speed reduction ratio of the hand-wound wheel train 34 (for example, in the conventional timepiece, the speed reduction ratio is 3 to 4, but in the present embodiment, it is 6). The reduction gear ratio can be set to the above), and the mainspring 1 can be a manual winding portion 3 that is easy to wind. (9) Since the mainspring 1 is provided with the slipping attachment 61 for preventing the mainspring 1 from being excessively wound by the automatic winding section 4, it is possible to easily prevent the mainspring 1 from being excessively wound, and also to prevent excessive winding. It is easy to prevent the mainspring 1 from being damaged. (10) The barrel wheel 10 which is a relatively large part in which the mainspring 1 is housed, and the generator 2 which is one of the other large parts are close to each other in a part in the circumferential direction of the electronically controlled mechanical timepiece. Since it is arranged in the circumferential direction, the arrangement space of the other portion in the circumferential direction, particularly the portion close to the outer peripheral side can be continuously used long in the circumferential direction although the width is narrow. 70 can be efficiently arranged. Further, since the circuit block 70 is arranged using such a space on the outer peripheral side, the circuit block 70 can be arranged so as not to overlap the generator 2 and the barrel wheel 10, and the plane size of the timepiece is maintained. However, it can be made thinner and further miniaturization can be promoted. (11) Further, since the circuit block 70 is efficiently arranged along the outer peripheral side of the timepiece, each train wheel 13 to 17 is provided.
Even if the wheel train consisting of, the hand-wound wheel train 3, and the automatic wheel train 4 are compactly integrated in a position surrounded by the generator 2, the barrel wheel 10, and the circuit block 70, the circuit block 70 does not overlap them. The watch can be kept thin. (12) Since the circuit block 70 is formed of a flexible FPC, in addition to being lightweight and thin,
It can be bent and placed in the thickness direction of the watch. Therefore, it is possible to satisfactorily dispose the center portion sandwiched between the circuit seat 76 and the circuit receptacle 74 and the one end side portion connected to the coil lead substrate 29 even if the disposition positions are vertically displaced. Can flexibly accommodate a narrow space. (13) The circuit block 70 has a planar crescent shape, and the IC 72 and the crystal oscillator 73 are mounted in the wide center portion between the both ends, so that a high-density wiring pattern around these components can be reliably and favorably formed. Therefore, the productivity and reliability of the circuit block 70 can be improved.

B. Second Embodiment FIG. 7 is a sectional view showing a main part of an electronically controlled mechanical timepiece which is a timing device according to a second embodiment of the present invention. The second embodiment is the transmission wheel 44 of the first embodiment.
In addition, a slip mechanism 62, which is a mechanism for preventing excessive winding of the mainspring 1, is provided.

In the slip mechanism 62, the transmission gear 44a and the pinion 44b, which form the transmission wheel 44, are separated from each other, and the spring member 44c is arranged between the pinion 44b and the transmission gear 44a. When a torque greater than a predetermined rotational torque is applied to the transmission gear 44a, the transmission gear 44a and the pinion 44b are slipped.

More specifically, on the back surface of the transmission gear 44a, a concave portion 4 is cut out from the end surface of the pinion 44b toward the outer periphery.
4d is formed. A spring member 44c made of a disc spring or the like is arranged in the recess 44d, and both ends thereof are brought into contact with the transmission gear 44a and the pinion 44b, respectively, and the transmission gear 44a rotates integrally with the pinion 44b by the spring member 44c. Pressed against the flange. Therefore, while the mainspring 1 is being wound by the automatic winding section 4, the transmission gear 44a and the pinion 44b are integrally rotated by the urging force of the spring member 44c. On the other hand, when a torque equal to or more than a predetermined rotation torque is applied to the transmission wheel 44 in a state where the mainspring 1 is completely wound up and further winding is attempted, the contact portion between the transmission gear 44a and the pinion 44b slips. The torque is set not to be transmitted to the ratchet wheel 11. As a result, excessive winding of the mainspring 1 is prevented.

Thus, by providing the transmission wheel 44 with the slip mechanism 62 for preventing the mainspring 1 from being overwound, it is necessary to provide the mainspring 1 with a large-scale slipping attachment 61 as in the first embodiment. There is no. That is, as shown in FIG. 8 and FIG. 9, a hook portion 63 formed by being folded back is formed at the final end of the mainspring 1, and the hook portion 63 is formed on the inner surface of the barrel wheel 10. A simple structure for hooking onto 63A is sufficient.

When the winding is performed by the manual winding portion 3, the torque is directly transmitted from the round hole transmitting wheel 36 of the manual winding wheel train 34 to the square hole wheel 11 via the pinion 44b. The mainspring 1 is wound up like a winding clock.

According to the second embodiment as described above, the same effects as (1) to (8) of the first embodiment can be obtained, and (14) the slip mechanism 62 is provided on the automatic winding section 4. Therefore, the conventional slipping attachment 61 becomes unnecessary, and when the barrel wheel 10 of the same size is used, the effective length dimension of the mainspring 1 can be increased. As a result, the operation duration of the timepiece can be extended.
For example, in the present embodiment, compared to the first embodiment,
The duration could be extended by about 5 hours. Also,
When it is not necessary to extend the duration, the barrel complete 10 can be made smaller and the timepiece can be made smaller. (15) Since the slip mechanism 62 is provided on the gear (the transmission wheel 44) one step before the mainspring 1, the slip torque can be reduced to, for example, about 1/5 of the case where the mainspring 1 is provided, and it is as simple as a disc spring. A spring structure can be adopted, and one with excellent durability can be easily manufactured. (16) In the case of manual winding, the operator can detect the torque applied to the mainspring 1 as in a normal manual winding timepiece.
Excessive winding does not occur. Conventionally, when a self-winding watch is manually wound, even if the mainspring is full, the slipping attachment works and the mainspring slips.
There is a problem that the operator does not know where to stop winding the mainspring and continues to wind the extra winding. However, in the present embodiment, the operator can detect the torque applied to the mainspring 1 as in the case of the hand-wound watch. , The problem of continuing extra winding can be solved.

C. Third Embodiment FIG. 10 is a sectional view showing a main part of an electronically controlled mechanical timepiece, which is a timing device according to a third embodiment of the present invention. In the third embodiment, the automatic winding lever 45 of the first embodiment is provided with an overwinding prevention mechanism for preventing the spring 1 from overwinding. Specifically, the arm portion 45b of the automatic winding lever 45 is formed with a curved portion 45e which is a deformed portion. The curved portion 45e serves as an excessive winding prevention mechanism. That is, when the mainspring 1 is all rolled up and further winding is attempted, the pawls 4 of the automatic winding lever 45 are rotated in order to rotate the transmission wheel 44.
Even if a torque greater than a predetermined torque is applied to 5c and 45d, the curved portion 45e is deformed, so that the claws 45c and 4d are not deformed.
5d does not apply a torque above a predetermined torque,
As a result, the transmission wheel 44 does not rotate. As a result, excessive winding of the mainspring 1 is prevented.

According to the third embodiment as described above, the same effects as (1) to (8) of the first embodiment can be obtained, and (17) the automatic winding lever 45 is provided with an excessive winding preventing mechanism. Since the curved portion 45e is provided, the excessive winding of the mainspring 1 can be prevented easily and reliably by the curved portion 45e. In particular, the slipping attachment 61 and the slip mechanism 62 require maintenance of the frictional state in order to utilize friction, but in the present embodiment, deformation of the automatic winding lever 45 is utilized, and friction is utilized. Since it does not do so, management such as lubrication is unnecessary, stable operation for a long period of time can be realized with a simple and space-saving configuration, and the cost of the watch can be reduced.

The present invention is not limited to the above-described embodiments, but includes other configurations and the like that can achieve the object of the present invention, and the following modifications and the like are also included in the present invention.
For example, the excessive winding-up prevention mechanism is not limited to those in the above-described embodiments. For example, the rotary weight 41 and the ball bearing 47 may be configured to slip with a certain torque or more to prevent excessive winding of the mainspring 1. Also,
The square ratchet wheel 11 may be composed of two bodies and configured to slip with each other at a torque equal to or higher than a certain torque to prevent excessive winding of the mainspring 1. Further, the eccentric pin 4 provided on the rotary weight 41
2 is provided on the spring member, and when the elastic force of the spring member is set and the reaction force of a certain value or more is received from the automatic winding lever 45, the eccentric amount is set to 0 and the mainspring 1 is not wound up. Excessive winding of the mainspring 1 may be prevented. Further, a spring portion is provided around the hole stone of the automatic winding lever 45 that engages with the eccentric pin 42, and when the reaction force exceeds a certain value, the spring portion is deformed and the operating amount of the automatic winding lever 45 is set to 0.
May be configured not to be wound up to prevent excessive winding of the mainspring 1. In short, the over-winding prevention mechanism may be any mechanism that prevents over-winding of the mainspring 1, and its shape, structure, and the like may be appropriately selected in practice.

Further, as the manual winding wheel train 34, mechanical energy is input to the mainspring 1 via the automatic winding wheel train 43, but the invention is not limited to this. Alternatively, the automatic winding train wheel 43 may be independently provided, and mechanical energy may be input to the mainspring 1 for each train wheel. However, as the manual winding wheel train 34, if the mechanical energy is input to the mainspring 1 through the automatic winding train wheel 43, the automatic winding train wheel 43 can be shared by the respective winding upper portions 3 and 4. This is preferable in that the number of parts of the timepiece can be reduced, and thus the timepiece can be more easily downsized and the layout can be made appropriate.

Further, the energy holding amount display section is not limited to the above-described mainspring remaining amount display mechanism 5, and, for example,
A mainspring torque display mechanism for displaying the torque value of the mainspring 1 may be used, and the configuration and method of the display may be appropriately determined upon implementation. Further, the energy holding amount display unit is not limited to the one using the planetary gear mechanism and the pointer, and for example, the energy holding amount is obtained by detecting the brake amount with an IC or the like that controls the rotation of the generator 2.
You may make it display on a suitable display part, such as a liquid crystal and a sound.

Further, the energy holding amount display section (mainspring remaining amount display mechanism 5) does not necessarily have to be provided. Also in this case, since the mainspring remaining amount display mechanism 5 is arranged between the barrel barrel 10 and the generator 2 independently of the other winding heads 3 and 4, it is only necessary to remove the mainspring remaining amount display mechanism 5. It is good and there is no need to adjust the arrangement of other parts. For this reason, even if the specifications of the presence or absence of the mainspring remaining amount display mechanism 5 are different, the other manual hoisting portions 3, automatic hoisting portions 4, the generator 2, etc. can be made common and manufacturing is facilitated, and the cost can be reduced. . Similarly, even in the case of manufacturing a timepiece without the automatic winding part 4, it is sufficient to simply remove the automatic winding lever 45 and the rotary weight 41, and the other parts can be shared, which facilitates the manufacturing and reduces the cost. Can also be reduced.

Further, as the mechanical energy storage section,
Not limited to the mainspring 1, rubber, a spring, a weight, or the like may be used, and may be appropriately set according to the object to which the present invention is applied. Further, the mechanical energy manual input unit is not limited to the manual hoisting portion 3 of the above-described embodiment, and may be appropriately set according to the type of the mechanical energy storage unit and the like. Further, the automatic mechanical energy input section is not limited to the automatic winding section 4 using the automatic winding lever 45, but may be an all-gear type, and the mechanical energy is automatically stored in the mechanical energy storage section such as the mainspring 1. Anything can be input to. Further, as a mechanical energy transmission device for transmitting mechanical energy from a mechanical energy storage unit such as a mainspring to the generator 2,
The invention is not limited to the train wheel as in the above embodiment, but may be a friction wheel, a belt (timing belt or the like) and a pulley, a chain and a sprocket wheel, a rack and a pinion, a cam, or the like. It may be appropriately set according to the above.

Furthermore, the generator is not limited to a generator that rotates a rotor to generate electric power by electromagnetic conversion, but another type of generator such as a piezoelectric generator that applies stress to a piezoelectric element (piezo element) to generate electric power. May be used.

Further, the time information display device is not limited to a pointer, and a disc, an annular shape or an arc shape may be used. Further, a digital display type time information display device using a liquid crystal panel or the like may be used.

The timekeeping device of the present invention is not limited to an electronically controlled mechanical timepiece, and various kinds of wristwatches such as a timepiece that operates the step motor by using the electric power generated by the generator 2, a clock, a clock, and the like. Various clocks are acceptable. Further, in addition to the battery, the present invention can be applied to a timing device including the mainspring 1 and the generator 2 as an auxiliary power source. Since such a time measuring device of the present invention can be used without a battery or the like, it can also be used as a time measuring device for outdoor or disaster.

[0071]

As described above, according to the timing device of the present invention, the mechanical energy manual input unit and the mechanical energy automatic input unit are provided on the opposite side of the mechanical energy storage unit from the power generation unit. Since the power generation unit and the mechanical energy automatic input unit do not overlap with each other because it is provided at the position, it is not necessary to shift the position so that the power generation unit does not overlap with the mechanical energy automatic input unit. The space efficiency is improved, the area of the movement can be reduced, and the timing device can be downsized.
